Gas burner



Patented Nov. 3, 1931 UNITED STATES PATENT OFFICE LORAN F. DOEN, OF CLEVELAND, OHIO, ASSIGNOR TO AILHE CLEVELAND* HEATER COM- PANY, OF CLEVELAND, OHIO, A CORPORATION F OHIO GAS BURNER Application filed January 12, 1927. Seria1'No.'160,746.

This invention relates to improvements in gas burners and 1n particular ignition pilot burners.

Itis the object of this invention to provide a simple inexpensive gas pilot burner the flame of which cannot be readily extinguished by drafts and other conditions encountered in the appliance with which the pilot is used.

The drawing shows a side elevation in section of the pilot burner'embodying my invention.

The pilot burner illustrated comprises a body portion l, threaded at its lower end for *i connection to a gas supply line (not shown) and is provided with a central bore or passageway 2 terminating at its upper end in four downwardly projecting orifices or holes 5. The body l supports a shell or cap i positioned above and extending beyond the Vupper open end of a sleeve 3 which is carried at its lower end on the body 1, and the upper portion of which is spaced apart from said body to define an open-ended chamber.

The sleeve 3 is provided with four circumferentially spaced holes 6. These holes are so positioned with respect to the holes or orifices 5 of the body l that part of the gas stream issuing from the orifices 5 will strike against the edge of the holes 6. The effect of this action is that a portion of the gas pass-es out of the holes 6 and a portion of it is trapped within the chamber deiined by the ksleeve 3 and the body 1 and issues from'the upper opening delined by these elements.

By reason of this construction, a pilot light is provided in which there are four flames issuing from a like number of holes spaced around the burner and a single annular flame which issues from between the shell or cap 4 and the sleeve 3. This arrangement pro- Vides a pilot burner, not easily extinguished by strong drafts, variation in gas pressure, burner yexplosions; and other accidental causes of pilot light extinguishment.

Further, it is to be understood that the particular forms of apparatus shown and described, and the particular procedure set forth, are presented for purposes of explanation and illust-ration and that various modiiications .of said apparatus and procedure can be made without departing from my invention as definedin the appended claims.

What I claim is:

' 1. A gas burn-er comprising a burner body provided with a central gas passageway and downwardly inclined communicating orifices, a cap or shield for the top of said body and a ported housing encircling and carried by said body, saidcap spaced above and overhanging the ported housing.

2. A gas burner comprising a. burner body provided with a central gas passageway and downwardly inclined communicating orifices, an open-ended housing carried by and encircling said burner body having ports opposite to said orifices said ports and orifices beingV so adjusted that part of the gas stream issuing from each orifice passes directly through the opposite port and part of the gas stream impinges on the edge of said portand then issues from the open end of said housing.

3. A pilot burner comprising gas conducting and distributing' means providing a plu rality of radially disposed horizontal flame supportingports and an annular flame supporting aperture overlying and in lighting proximity to said ports, whereby said burner provides a plurality of laterally directed flames and an annular flame thereabove.

4. A pilot burner adapted to support a plurality of radially disposed flames and an annular flame in lighting proximity thereto comprising a burner body having a discharge opening in the upper portion thereof, a ported member adapted to be carried by said body defining a chamber therewith open at the top and communicating with said discharge opening` and a cap or shield carried by said burner body spaced above said member to definean annular opening in communication with said chamber.

In testimony whereof I hereunto affix my signature.

LORAN F. DOEN.
